Description
Technical field
The present invention relates to technical field of textile production, are a kind of composite-type terylene long filament and its processing method specifically.
Background technique
Polyester fiber is commonly called as " terylene ".It is that the polyester as made of organic dibasic acid and dihydric alcohol polycondensation is resulting through spinning
Synthetic fibers, abbreviation PET fiber, belong to high-molecular compound.It is invented in nineteen forty-one, is the first big product of current synthetic fibers
Kind.Polyester fiber biggest advantage is that wrinkle resistance and conformality are fine, intensity with higher and elastic recovery capability.Its is strong
Durable, wash and wear, not adhesive hair.
Polyester (PET) fiber be by each chain link in macromolecular chain by ester group be linked to be fibre-forming polymer spinning synthesize fibre
Dimension, polyester english abbreviation are PET.Fiber of the China by polyethylene terephthalate content greater than 85% or more is referred to as washed
Synthetic fibre, there are many external product name, as the spy up to gram synthetic fibre (Dacron), Japan in the U.S. holds in the palm the Te En of synthetic fibre (Tetoron), Britain
Block (Terlenka), the La Wushan (Lavsan) of the former Soviet Union etc..Early in 1894 Wall orchid moral (Vorlander) use succinyl chloride
The polyester of low relative molecular mass is made with ethylene glycol；Encke grace (Einkorn) polycarbonate synthesis in 1898；Carlow pool this
(Carothers) synthctic fat adoption ester: the polyester of synthesis is mostly aliphatic compound in one's early years, relative molecular mass and molten
Point is all lower, soluble easily in water, therefore does not have the use value of textile fabric.The Weinfield (Whinfield) of nineteen forty-one Britain
Polyethylene terephthalate has been synthesized with dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) with Dick loose (Dickson)
(PET), the fiber of function admirable can be made in this polymer by melt spinning.The nineteen fifty-three U.S. founds the factory first produces PET fibre
Dimension, it may be said that PET fiber is to develop a kind of later fiber in big kind synthetic fibers.
